can somebody help me out on how to interface an 8051 ic to a 8742 keyboard controller ic..?? i am connecting a keyboard through a ps2 connector to the board...this interface is controlled by 8742..how do i obtain the keys pressed at 8051?
But how would interfacing it to a C51 differ from interfacing it to anything else?
Do you think that the 8742 behaves any differently when connected to a C51 than when connected to anything else?
Similarly, do you think that the C51 behaves any differently when connected to an 8742 than when connected to anything else?
General procedure for interfacing anything to anything else:

You do have the Datasheet for the 8742, don't you...?
